Abstract

The invention relates to the technical field of virtual display equipment, and discloses a head-mounted type display apparatus. The head-mounted type display apparatus comprises a binocular vision mechanism, a focal length adjustment mechanism and a terminal fixation mechanism, wherein the binocular vision mechanism is connected with the terminal fixation mechanism through the focal length adjustment mechanism, the focal length adjustment mechanism comprises multiple successively connected sleeves, and adjacent two sleeves are in slidable connection through one sliding connection assembly. The structure of the focal length adjustment mechanism becomes relatively simple, such that the volume of the head-mounted display apparatus is reduced, the weight is reduced, a user can conveniently carry the head-mounted display apparatus, and user experience is improved.

Description

technical field [0001] The present invention relates to the technical field of virtual display devices, in particular to a head-mounted display device. Background technique [0002] Virtual reality technology is a new comprehensive information technology emerging at the end of the 20th century. It is an advanced and digital human-machine interface technology. The immersive feeling in the future will fundamentally change the boring, blunt and passive status quo between humans and computers, and create a new research field for human-computer interaction technology. [0003] At present, a common virtual reality device such as a head-mounted helmet device can close people's vision of the outside world by wearing a head-mounted helmet device, and guide users to have a feeling of being in their virtual environment; The imaging principle of the device adopts the method of "lens + screen". Among them, the focus adjustment equipment in the device has a large number of components and...
